CHARLES REED, OF PORTLAND, INDIANA, ASSIGNOR OF ONE-HALF TO JOHN R. REED, OF SAME PLACE.

HOOP-RACKI'NG MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 653,528, dated July 10, 1900.

Application filed .Tuly 2'7, 1899.

To all whom t may conceive:v o

Be it known that I, CHARLES REED, of Portland, in the county of Jay and State'of Indiana,have invented a new and Improved Hoop- Racking Machine, of which the following is a full, clear, and exact description.

My invention relates to an improvement in devices for racking or splitting hoops from a bar, and comprises the novel features hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the gures.

Figure l is a side elevation of my device. Fig. 2 is a longitudinal sectional elevation. Fig. 3 is a perspective view showing the end of the bar from which the hoops are made prepared for introduction in the machine. Fig. 4 is a plan view of my device, showing the standard carrying the operating-shaft in section; and Fig. 5 is a sectional elevation taken upon the line 5 5 of Fig. 2.

The object ofiny invention is to produce a machine which will rapidly splitohoops from bars of wood. In making hoops from lumber it is customary to split the lumber into bars which are of a thickness corresponding with the width of the hoop and of such a width as to make a number of hoops. These are then checked at one end and then split up into separate hoops. My machine takes bars which are thus prepared by being checked at the ends and splits them up into hoops by passing the bar through the machine.

The machine is provided with a suitable framework, within which is secured a bed, which consists of two parts B and C, slightly offset from each other. In the upper part are placed two sets of rollers H and h, one of the rollers being connected with a feed mechanism, so as to advance the bar to the breakerhead. At the end of the upper section of the bed is placed a fulcrum-block G, the upper end of which is preferably covered with a corru gated metal plate, as clearly shown in Fig. 2. This fulcrum-block rests upon an eccentricpin g, which is connected with a lever g. By operating it the elevation of the fulcrum-block may be slightly varied to adjust the device for use with bars of different thickness. The

Serial No. 725,263. (No model.)

set of rollers h which are neXtvto the fulcrum -block are grooved or provided with flanges separated a distance equal to thethickness of the bars which are being used, so that the bar'cannot twist or roll while being'operated upon.

J ust above the fulcrum-block G andk at a level corresponding with the level of the lower portion of the upper rollers H and h is a transverse bar I, which is firmly secured to the sides A of the machine-frame. The sides A of the machine-frame are preferably made about six inches apart. The grooves in the rolls h, which receive the bars, are located in the center o f theirlength. The bars are also guided to these grooves by means of bevel guide-plates b, which are secured in the section B of the bed. Pivoted in the opposite or rear end of the frame A is the breakerbar D. This is pivoted upon 'an eccentricpin d, which also has a crank-arm d secured thereto, by means of which the breaker may be adjusted toward orV from the f ulcrumblock G. The swinging or working end of the breaker-bar D reaches to near the ful- Crum-block G and is rounded, the rounded Working surface being preferably covered with a corrugated metal plate D', as shown in Fig. 2. The corrugations in the plates upon the fulcrum-block and breaker-bar are designed to prevent slipping upon the hoopba'r while being operated upon.

Upon suitable standards A', secured to the frame, is mounted a shaft E above the bed. This shaft has a pulley-wheel E secured thereto and adapted to receive a belt, by which means it is turned. This shaft has an eccentric e secured thereto and having an eccentric-strap e about the eccentric and connected with a rod e2, which is pivoted to lugs es, secured to the swinging end of the breaker D. By this means the breaker is given a vertical reciprocating movement.

The two arms d and g', by which the breaker and the fulcrum-block are adj usted in position, are connected with a common rod K, which leads to the front of Athe machine and is connected with a hand-operated'lever K', so that both may be adjusted simultaneously. The upper rollers H and h of each set are mounted in frames H and h', so that they may IOO be adjusted vertically to accommodate them to bars of different thickness. These frames are mounted to slide vertically in suitable guides upon the machine-frame and are pivotally secured to a lever J, said lever being pivoted at one end to one of the standards A and at its other end is connected with a rod having weights J thereon, by which means the rollers H and 7L are held down in position upon the hoop-bars.

One of the feed-rollers H, being preferably the lower one, is connected with the shaft E in such manner as to give a step-by-step movement to the hoop-bar. At its outer end it is provided with a ratchet-wheel L, which is engaged by a pawl M upon a lever L. A stoppawl M' is also provided, which engages the ratchet -wheel to prevent backward movement. The pawl-lever L is slotted and has a pin N mounted to slide therein and adapted to be connected with an operating-link F2. This operating-link is connected to said pin by passing through a hole therein and is secured in place therein by a set-screw entering one side of the pin. The pin N is also secured to a link O, by which it may be readily adjusted to different positions in the lever L. The link O is connected at one end to a lever P, which is mounted upon the frame A and has a rod E connected thereto and leading to a hand-operated lever P2, located at the forward end of the machine. By this means the throw of the pawl-lever L may be varied by moving the pin N toward the pivot or to the outer end thereof, as desired.

The link or rod F2, by means of which the pawl-lever L' is reciprocated, is connected at one end with an eccentric-strap F', which is mounted upon an eccentric F, secured to the shaft E. In Fig. 2 a hoop-bar R is shown in position.

My device is operated as follows: The hoopbars are first checked at one end, as shown in Fig. 3. They are then introduced to the machine, the checked end first, said end being passed through the feed and guide rollers H and h. The checked end passes over the fulcrum-block G until it is engaged by the reciprocating breaker D. This end is then bent downwardly, the body of the bar being firmly held by the rollers and the bar I. As the end of the bar is bent downward the lines of weakness started in the bar by the checking are continued by the bending operation, thus extending the splits farther from the end of the bar. The bar is fed forward by short stepby-step movement, and at each forward movement the breaker is brought down, thus bending the bar and continuing the splits therein. By this means the bar is split from end to end.

By placing the bar I, which restrains the upper side of the hoop-bar, close up to the breaker and immediately over the fulcrumblock G the bars may be split very close to the end or entirely out.

Having thus fully described my invention,
